Problems solved by technology

[0002] At present, remote data collection and transmission are needed in all walks of life, especially in industries such as environmental protection, which often need to collect data in some harsh environments. At this time, if ordinary telephone transmission is used, it will get twice the result with half the effort
Moreover, the coverage area is small, there are many dead angles, it is troublesome to use, and the efficiency is not high
